| Abstract:
The last decade has seen the rise of the molecular approach to self-incompatibility in almond, but not so successful with self-compatibility, which remains unmapped in the almond genome. The concept of autogamy has emerged as closely linked to self-compatibility in order to have a good agronomical performance of a self-compatible cultivar in single cultivar orchards in the absence of pollinating insects. New self-compatible forms have been identified among distant almond populations, thus broadening the possibilities of utilization of other sources of self-compatibility in almond breeding. All these aspects are reviewed in order to focus the different breeding programmes aiming to include self-compatibility in almond, as well as to mention the new cultivars released from these programmes. Some questions, however, especially the transmission of self-compatibility in certain crosses, still waite for an adequate answer. On the other side, the transference of some self-compatible cultivars to the growers has been highly successful for the improvement of almond production. | |
